How do I set up W.o.T to join the Public Test Server?

Can someone tell me what steps to take to be able to join the 0.8.0 Public Test when it launches next week? Do I make a copy of my existing WoT installation, what do I need to change for it to be able to patch to 0.8.0 and join the test server?

If you want to keep the original 7.5 WoT client you will have to make a copy of it, then once the test server launches there will be a patch to download which you will have to apply on the copied version of your game.

The last few tests have all been different, some wanted a copy of your existing install, some had a complete standalone test client to download. With this being a major update beyond a bit of interface tweaking and new tanks it's likely to be the latter.
